nested haah in perl
In Perl, you can create nested hashes by assigning a hash reference to a hash key. Here's an example:
my %hash1 = (
key1 => {
nested_key1 => 'value1',
nested_key2 => 'value2'
},
key2 => {
nested_key3 => 'value3',
nested_key4 => 'value4'
}
);
In this example, %hash1
contains two keys (key1
and key2
), and each key is associated with a hash reference. The hash references represent the nested hashes.
